Are you afraid of water or aren't you? Learn about the composition of the plasma membrane of a cell. The clip describes why the plasma membrane is structured in this way and how this formation is useful...

Is it all about concentration? Explore the description of a semipermeable membrane with a video highlighting illustrations of the membrane and its function. See how concentrations of molecules move back and forth across the...

The inner life of a cell is laid out like a science fiction film. With dramatic music playing in the background, show your learners how the organelles interact and perform. This highly scientific clip is very detailed and is geared...

Pump it up! Learn how a special protein called the sodium-potassium pump allows certain molecules or ions to pass through a cell's plasma membrane. 

Provide your class with a simple explanation of channel protein movement. Pupils view a short video segment and explore how channel proteins move ions across a plasma membrane. They conclude the lesson with a short discussion of...

Has your class wondered about the eccentricities of the endomembrane system? A video segment helps pupils investigate the nuclear membrane, smooth and rough endoplasmic reticulum, and Golgi apparatus. 

How do you get there from here? Explore the three main types of transport within a cell: active, passive, and bulk transport. Reinforce concepts of previous videos with this ninth video of a 10-part series.

Watch as the Khan Academy explains why red blood cells are efficient carriers of hemoglobin and explains the difference between pulmonary arteries and veins. This thorough video, complete with excellent explanations and diagrams, will...

This lesson will describe the structure and function of the plasma membrane of a cell.

Learn all about the complex components of the cell membrane in this video lecture. Understand how the components of the phospholipid bilayer allows the cell membrane to be modeled by a fluid mosaic model. [8:47]

This lesson will describe how the differences in concentrations of ions across a plasma membrane set the stage for a nerve impulse. It is 1 of 2 in the series titled "Membrane Potential."

A sometimes humorous look at plant and animal eukaryotic cells. Learn about specialization and compartmentalization in cell biology through this YouTube video. [9:16]
